Ofcom consultative document looks at
possible new use for 24 and 77GHz
Another consultative document has been published on the Ofcom website.
This one is entitled ‘Notice of Ofcom’s proposal to exempt automotive
short range radar users at 79GHz from wireless telegraphy licensing’,
and proposes to use 77 - 81GHz for licence-free car radars.
The document states that “Designating the 79GHz band for licence
exempt use by SRR equipment does not result in any exclusion of other
uses of this band in the future. In other words, when we make exemption
regulations users should bear in mind that users are quite likely to be
sharing the relevant spectrum with present and future users.”
The Amateur Services currently have a Primary allocation at 77.5 - 78.0GHz.
On 24GHz, the consultation document reads: “The European Commission,
Member States and the automotive industry are also currently considering
allowing limited use of the 24GHz band, covering 21.5 - 26.5GHz for SRR
equipment.
A final decision on the 24GHz band has not yet been reached. This may
be the subject of further exemption regulations in due course." The
Amateur Services have a Primary allocation at 24.0 - 24.05GHz.
Comments on this document are due by 14 January to: Christina Spyrelli,
Ofcom, Riverside House, 2a Southwark Bridge Road, London SE1 9HA, or e-mail:
